Abstract (en)
[origin: WO8200823A1] 3,6-bis(carboethoxyamino)-2,5-diaziridinyl-1,4-benzoquinone, sometimes known as "AZQ" is prepared by reacting a dialkylpyrocarbonate with a diamino hydroquinone to form 2,5-dichloro-3,6-bis (carboethoxyamino)-1,4-hydroquinone. The latter compound is oxidized to form the corresponding benzoquinone, which is reacted with an aziridinyl compound to produce 3,5-bis(carboethoxyamino)-2,5-diaziridinyl-1,4-benzoquinone.
